Clarify and avoid compiler warning

Browse Source 
clang 3.4.1 on FreeBSD gave this warning:

    nmap.cc:3064:48: warning: use of logical '||' with constant operand
          [-Wconstant-logical-operand]
        return file_is_readable(filename_returned) || 1;
    nmap.cc:3064:48: note: use '|' for a bitwise operation

Changed to match the intent: return 1 if file_is_readable returns 0, otherwise
return that non-0 value.
